claims. (01. 24.21355) The invention pertains to automatic yarn windsing machines of the type commonly known as spoolers and exemplified inColman Patent No. 1,267,977 issued May 28, 19 18. In such winders amechanism known as a winder tending mechanism is arranged to travel intoassociation successively with a series of units for windingyarn frombobbins onto cheeses. In the operation of the machine, when the yarnsupply from a given bobbin is interrupted through exhaustion orbreakage, or when the yarn mass attains a predetermined diameter, thecheeses are shifted automatically from a running position to athrown-out position. One of the functionsot the winder tending mechanismis to restore -torum ning position the cheeses that have been thrown outdue to exhaustion or breakage of the yarn, and the present inventionrelates to an improved means for accomplishing this result.

Heretofore the restoration of the cheeses from thrown-out to runningposition has been accomplished by means of a device known as a plowmounted upon the tending mechanism and operative in the travel of suchmechanism past the winding units. In this operation, the plow engageseach cheese arm at a point relatively close to the pivot, and with a camaction swings the arm upwardly over center to its runningpositiona Theprimary object of the present mvention is to provide a lifting device ofa character such as to avoid the wear incident to the .camming action ofthe plow upon the cheese arms. a

Anotherobject is to provide a lifting device driven in timed relationtothe travel-of the mechanism and activein an upward direction to liftthe cheeses bodily for movement 'from the thrown-out position into theirrunning positions.

Still another object is to provide a cheese lift.- ing device of thecharacter last above referred to in which the actuating means isoperative through a stroke which is short as compared to the range ofmovement through which the .cheese passes.

A further object is to provide for the perform.- ance of the liftingfunction in two steps by'successively operating liitingmemberssoarranged that while one of the members is acting to impart the finalthrust .to a cheese lacing operated upon, th ther member i bein restoredto retracted position for n a ment with the cheese of the next windingunit as the tending mocha, nism advances along the winder. i

The objects of the invention thus generally stated, together with otherand ancillary seam tages, :are attained by the construction and ar- 2.rangement shown by way of illustration in the accompanying drawingswherein:

Referring now to Figs. 1 and -3 of the drawings, the winder tendingmechanism comprises generally a carriage l arranged to travel upon amain supporting frame 8 for successive associattion with a series ofwinding vunits, the main frame having a rack 9 with which meshes a drivegear H] of the traveling mechanism. Eaghof the winding units comprises asupport fora cross wound yarn mass or cheese (2 produced icy the wi di g9f ram ,1! m ue e si b ns 2 the h es be sz o ma y sup rte o a o atindrum H provided with a traversing groove 12 (Fig. 3).

Andfor the purpose of ng the speed with which the ,l-iiiin id i ss machinedto (be actuated in ordert oar-at iner-s imesive cheeses without reducingthe rate of travel of the tending mechanism, the lifting function ispreferably accomplished in two successive steps by successivelyoperating members so timed that during the final portion of the liftingoperation performed by one member the other member is being retractedinto position for engagement with the next succeeding cheese.

In the present exemplary embodiment of the invention, the improvedcheese lifting and positioning means comprises two lifting members l5and It pivotally mounted on the carriage 'l and arranged for operationin timed relation to each other and to the travel of the carriage. Theactuating means for the two members comprise two crank disks I? and I8,the latter being provided on its periphery with teeth I8 to form a spurgear for driving purposes.

The members I5 and I5 preferably engage directly with the cheesesthemselves and are therefore in the form of curved polished plates.latter are mounted upon arms I9 and 29 pivotally supported in spacedparallel relation on a shaft 2| and respectively having rigid therewith,

crank arms 22 and 23. The arms I9, .22, and 29, 23 constitute two bellcranks respectively connected by links 24 and 25 with studs 26 and 21 onthe disks I1 and I8. The disks are fast upon a shaft 28 suitablysupported in the carriage i, and the studs are so positioned relative toeach other as to cause the members l5 and I6 to operate successively.The two members are spaced apart in the direction of travel of thecarriage and so timed that while the member I6 approaches its verticalposition (Figs. 1 and 2) whereby to shift the cheese over center, theother member I5 has completed its portion of the lifting function andstarted to move reversely into position beneath the succeeding cheese(see Fig. 1). As shown in Figs. 3 and 4, the arms I5 and I6 are offsetin the direction of travel of. the carriage. arm I5 to occupy a positionin advance of its actuating disk I! and link 24 so as to clear the.

latter in the fully retracted position of the arm (see Fig. 2)

It will be understood that the shaft 28 carrying the disks IT and I8 isdriven in timed relation with the travel of the carriage. For thispurpose the spur gear constituting the disk I8 is driven through gears29 and 30 (Fig. 3) the latter fast on a shaft 3| parallel with the shaft28 and suitably journaled in the carriage. For driving the shaft 3i ashaft 32 extends vertically through a frame member 33 of the carriage,being conheated at its lower end with the shaft 3| by bevel gearing 34.At its upper end the shaft 32 is connected by bevel gearing 35 with adrive shaft 36 carrying a pulley 31 which is driven by a belt 38 runningto a drive motor (not shown) mounted on the carriage. The vertical shaft32 has a pinion 39 fast thereon andmeshing with the drive gear II] whichcoacts with the rack 9 in advancing the carriage relative to the severalwinding units.

Upon movement of the cheese over center through the operation of thelifting device, its supporting arm I3 moves into engagement with a stopmember 49 (Fig. 3). The latter preferably has a cam surface 49 shaped tocontrol the descent of the yarn mass into its position on the windingdrum as an incident to the advance of the carriage, all in the mannerset forth in said Colman Patent No. 1,27 6,977.

While the improved cheese lifting and positioning device performs thefunction of the cam The.

This is to permit the and therefore need not be described in detail.

the drum I I. At this time the first lifting memor plow heretoforeemployed, it is contemplated that as a safety measure such plow mayadvantageously be employed together with the improved lifting device.The plow is preferably of the type shown in said Colman patent andcomprises a cam member 4| (Fig. 3) having a sloping surface 4I inclinedupwardly and rearwardly with respect to the direction of travel of thecarriage. It i adapted to engage with the cheese arms when the latterproject outwardly from their pivotal supports Id (Fig. l), and is soproportioned as to cause the arms to swing upwardly somewhatbeyond deadcenter as an incident to the movement of the carriage. In the event offailure on the part of the operator to place a cheese core upon any ofthe supporting arms I3 and thus render the members I5 and I6 of thelifting device ineffective, the plow 4I will engage with such arm andshift the same out of the path of the lifting device and thereby avoiddamage to the machine due to movement of the members I5 and it of thelifting device into engagementwith the arm. It will be understood thatthe lifting member I5 is timed to oper-.

lever arm I3 by the plow. Thus the lifting oper ation is performed bythe devices I5, I6, except in cases Where the operator has inadvertentlyfailed to place a cheese or core upon the arm I3.

It will be understood that as in the case of said Colman patent, thecheeses are shifted from their running positions in contact with thedriving drum or drums I I into their thrown-out positions 51automatically during the operation of the machine in response to threadfailure due to exhaustion or breakage or upon the attainment ofthe-cheese to a predetermined size. The means employed to perform suchthrowing out function may be the same as that disclosed in said patentIn brief it comprises a, sensitive feeler 42 responsive to the presenceor absence of the strand y passing from the bobbin 1) through a yarnclearing device 43 and thence over the drum I I to the cheese. Uponinterruption of the strand, the feeler 42 permits movement of a bail '44into the path of movement of a pawl 45. The bail is connected to thecheese arm I3 at a point eccentrically with respect to the shaft I4thereof, and

in the downward movement of the actuator the.

arm is swung upwardly, forwardly and thence downwardly, its downwardmovement being limitedby suitable interengaging stops (not shown)Summarizing the operation, it may be assumed that the parts occupy therelation shown in Fig.

1, with thefirst lifting member I5 about to move into position beneath athrown out cheese 0',

the immediately preceding cheese 0 having been restored to its runningposition in contact with her I5 occupie its retracted position so as tobe free to move beneath the cheese 0 and the second lifting member I9occupies a vertical position partially retracted from its extremeforward position (Fig. 2). As the carriage advances, member I5 is swungupwardly into engagement with the cheese c while the member I6swingsdown wardly to its extreme retracted position(F-ig. 2)

rangement is such that the lifting operation is performed in two steps.Were it not forthis,the speed of operation required of a single liftingmember would be doubled. Thus, .bythe construotion and arrangementemployedthe cheeses are lifted rapidly and without necessitating anyslowing up in the advance of the carriage.

It will also be seen that the objectionable wean ing of the plowheretofore experiencedis eliminated. At the same time the power requiredto perform the lifting operation is reduced; one of the factors in sucheconomy of power resulting from engagement with the cheese or itssupport at a point remote from its pivotal supporting axis it ratherthan adjacent thereto as inthc prior construction. Finally, engagementof the cheeses directly by the members it and it is ad vantageous inthat it serves tohold-the cheeses a ainst rotation during the liftingoperation.
